FWA510 failover issue

PeterUK

So I just tested the failover system for FWA510 even though I use IP Passthrough

So I hook it up with my WAN Ethernet and WAN backup and it seems to work but not that well.

So heres what happens ping to 8.8.8.8 is fine you go out Ethernet then ping fails and you go out Cellular then when ping is successful again you go out Ethernet all seems good right? well no

So in short what the connection check is set like 60 secs it forces all traffic that was going out Cellular to test Ethernet and will check for the number of check fail limit then if on reply to ping goes back to Cellular meaning their is a interruption as ping checks out Ethernet so the only bad workaround is set connection check high and check fail limit low.
